About Authentic Santorini — Local Host, Private Tours

About Us

Our philosophy

At Authentic Santorini, we believe the true essence of this magical island lies beyond its famous views. It lives in the stories, the flavors, and the people—hidden in the quiet corners of villages, in ancient traditions, and in every drop of its world-renowned wine.

We are storytellers, explorers, and lovers of Santorini. With over 15 years of experience, our passion is sharing the island in a way only locals can—guiding you through hidden gems, untouched villages, and secret spots where history, mythology, and tradition come alive.

With our certified wine connoisseur, we bring our expertise to every tasting and every journey, pairing Santorini's wines with its authentic flavors, farms, and culinary treasures. But our experiences go beyond wine—they are about feeling, tasting, and exploring the island's soul.

Join us to uncover Santorini like never before—through stories, flavors, traditions, and moments that linger long after the sun sets over the caldera.

Words from guests I had the pleasure to host

Great tour

Our tour guide and driver, Constantinos was by far the nicest and most amazing tour guide we ever had and we are avid travelers. He went above and beyond and this tour was amazing.

Great tour and guide!

Konstantinos was a fantastic tour guide and sommelier. He was very knowledgeable, entertaining and made the tour super fun! I couldn't recommend any more highly.

Thanks Gatos!

Best tour we've ever done. Anywhere. So much more than a wine tour if you make sure your guide is the kind, funny, super friendly, authentic Greek renaissance man Konstantinos "Gatos". He is Santorini's winery expert, historian, artist, and best comedian. We loved his happy heart, jokes, safe driving, and how he took us to the best "little known" spots afterwards and anywhere else we asked. He makes it a party. This is the one tour you do not want to miss. He is the best Santorini has to offer!

Best day in Santorini

We had the privilege of having Gatos as our wine-guide in Santorini! He is an amazingly charismatic and welcoming human being with a lot of stories and knowledge to share about wines and Santorini and so much more. His connection with people is to be admired, as he sees everybody and wants everyone to have a good time. Would definitely go on his tours again!

Great Guide Excellent Experience

We had a wonderful time with our guide Constantino. He is very knowledgeable and has a great sense of humor. We've done many wine tours around the world and this is perhaps the best.

Unforgettable Experience

What a superb experience! Gatos is an absolute legend and we couldn't have asked for a more perfect tour guide. He arrived promptly to collect us and took us to Argyros Winery for the first tour/tasting and then Karamolegos Winery afterwards. The wine tours were brilliant and we learnt a great deal about the process and enjoyed sampling the wines.

Magical Experience

My partner and I had an amazing afternoon and evening with Konstantinos. Being a wine connoisseur, he was able to provide additional information we didn't get from the winery. He went the extra mile for us, sharing his story and interesting information about Santorini and its magical secrets.

Amazing

Konstantinos was such an amazing guide. He made the experience very personal and intimate. There's no better guide than him.

Amazing tour & Tour guide

From the start, Constantino was absolutely amazing. His friendliness, professionalism, and overall knowledge of Santorini's history - coupled with the details of the wines we tasted - are second to none. He went above and beyond to make our experience unforgettable and we strongly encourage anyone who is interested to go on this tour!

Above, beyond, and than some!

Thank you Constantino for the most spectacular evening! Going on a wine tasting tour was atop our list of to-do's, and our evening with the three other couples and you as our guide completely blew any and all expectations we had out of the water.

A 10/10 experience!

If I could give this tour a 6/5, I would! This is a MUST DO tour for anybody visiting Santorini who is a wine-lover, and wants to get away from the crowds! Gatos our tour guide was phenomenal- he personally ensured the quality our experience was top notch!

Konstantinos- what a guy!

Heard amazing things about the wine tasting in Santorini and this tour did not disappoint! Konstantinos was the best host, so personable and great company- he went above and beyond any expectations! A must when visiting Santorini!
